What connector is this?

Jeep won't start, thought it might be because the Crankshaft sensor went out. When I went to take a look I noticed this connector has a cut wire... So before I swap anything I'm trying to figure out what this is.

97 Wrangler Sport, 4.0L Manual

It might be easier if you find the empty receptacle.

Does it look like it could go to the CPS? Is it up against the firewall?

The reason I ask is that I have the same thing if it is, and was about to post the same question. I also have a connector that goes nowhere. Mine is a 97 SE, 2.5l

There are lots of unused connectors throughout TJs, they are for all of the various options, transmissions, etc. that are available. I had a '97 but that picture is so close up that I can't place where it is.

It's up against the intake manifold on the firewall side. It looks like a 4 pin... I think the CPS is a 3 pin isn't it? It's below freezing outside and my light broke so having a hard time looking up close while holding my phone for light.

If you don't have ABS brakes, that could be the ABS brake system connector. The CPS connector does come up into the engine compartment from low under the driver's side firewall.

There's another connector right beside it I'm pretty sure is the CPS connector. I suppose if it's the break connector it would be the reason she won't start. I'm still hoping to figure out what it is so I know if I should fix the wire, I'll try and trace it today now that I have some light.

I got real familiar with those connections the other day doing a manifold swap. It looks to me like your upstream O2 sensor wire. Check the first sensor on exhaust and see if its disconnected. But, this wouldn't be the reason for a no start.

Yeah I just traced it down to the o2 sensor. Ordered a new one.

Did I buy the wrong part or remove the wrong part? The one on the bottom is what I pulled from my TJ. I thought I was pulling the CPS but they don't match so I'm now confused... The plugs match on the other end though.

One is for an automatic transmission, the other is for a manual.

Both items in your photo are CPS sensors which are 3 wires and as Jerry pointed out your old one is for a stick and the new one for an auto. The disconnected wire looks like it goes to your up stream O2 sensor. The sensor location is in the exhaust just below the exhaust manifold under the jeep.
